a) S is a "greater than" relation on the set of real numbers; i, e All x, y R, x S y iff x>y What type of relation it is? Is it reflexive, symmetric or transitive? Or of all types? How many relations can be formed from X to Y if X = {u, v} and b) Y = {a, b}. %3D Find all possible functions from X to Y in part b) and show them c) through arrow diagrams (5+2.5+2.5)
